Beneficiation method applied to superconduction magnetic separation of rare earth ore

The invention discloses a beneficiation method applied to superconduction magnetic separation of a rare earth ore, and aims to solve the technical problems of higher economical loss and resource wastecaused by lower recovery rate of a rare earth resource in a traditional rare earth beneficiation process. The substantial process of the beneficiation method is as follows: firstly, a raw ore of therare earth ore is crushed and grinded; the tailing discarding is performed on the rare earth ore in advance by centrifugal reselection; then, a reselected concentrate is grinded, and a superconductionmagnetic separator is used for superconduction weak magnetic separation to remove high-magnetism mineral impurities; then, superconduction strong magnetic separation is performed to obtain a rare earth rough concentrate; and finally, flotation is performed on the rare earth rough concentrate to obtain a high-grade rare earth concentrate. The beneficiation method greatly improves the sorting precision and efficiency, and re
